We've just released SlickUpload 4.1, with support for ASP.NET AJAX. SlickUpload 4.1 supports both the AJAX 1.0 extensions as well as the ASP.NET 3.5 AJAX extensions. You can now drop an UploadManger control on a page with an UpdatePanel and integrate uploading into ASP.NET AJAX applications.

If you’re putting the UploadManager control inside an UpdatePanel, you need to do the following:

• Put the UploadManager control in a seperate UpdatePanel from other controls that will be updated — ASP.NET AJAX overwrites the entire UpdatePanel whenever any control inside it is updated, which would clear selected files.
• Set the following attributes on the UpdatePanel control: ChildrenAsTriggers="false" UpdateMode="Conditional"
• Use a PostBackTrigger to connect to the upload button. If your upload button has an ID of “submitButton”, the triggers section of the UpdatePanel control should look like this:
  

  <Triggers>
    <asp:PostBackTrigger ControlID="submitButton" />
</Triggers>

We've also upgraded the Krystalware support forums. If you registered an account in the past and can't access it, request a password reset and a new password will be emailed to you.
